' [his invention relates-toria' direct mixer or ipparatus for forcing a boiler4 liquid, i. e.f

'do e or leakreventinc fluid, boiler P P e cleaner or any liquid intofav hotwater boiler,

under pressure and directly mixed with the' waterlthereinI inl connection with a hot-water or' steam-heating. system, without removing or draining the water or` exhausting' the"` lsteam from the. boiler or system, thus obviatin'g the o bj ections tof the yoldy method2 andi saving considerable. time, labor','and cost;

l to provide al device by'which theboiler plete-device, and

vliquid'or the like can' be readily placedy in a tank or container underpressure; to indi'- catethe pressurefso Vtha-tit can be seenfwhen the' inflation .is complete; to provide apres#- sure gauge and' protect the same from in'-; jury; to, provide a' construction'whicli in-` suresv discharge ofthe boiler liquidi' ahead of and without displacing the air; to provide a control for vthe"dischargeofthe boiler liquidi; t'o provide a novell adapter or coup ling* to= connect the device through itsy flex` iblehose ortube' to al boiler drain opening or faucet ini different-positions or crowdedplaces; .and to generally provi'de'anzimproved Adevice of the character specified; E.: 7 i
